I kēia manawa, hoʻohana nui nā mea hana waʻa molybdenum no ke kaha kiʻi ʻana i nā uwea maikaʻi i nā ʻāpana hoʻoheheʻe kū pololei a me nā ʻāpana sintered.

 Ma hope o kekahi mau makahiki o ka hoʻomaʻamaʻa ʻana i ka hana ʻana i nā pahu molybdenum, ke manaʻoʻiʻo nei mākou ʻo ka manaʻo nui ma luna o nā crystals strip β Ammonium molybdate ʻoi aku ka maikaʻi o ka hopena ma ke ʻano he mea no ka hoʻomaʻamaʻa hou ʻana i nā ʻāpana hoʻoheheʻe kūpaʻa i hana ʻia e ka hōʻemi ʻana a me ke kaomi ʻana me ka ʻenehana ʻenehana. I kēia manawa, hoʻohana pinepine nā mea hana molybdenum strip ma Kina i kēia mea i mea no ke kaha kiʻi ʻana i nā ʻāpana molybdenum uea maikaʻi. Ma waho aʻe o ka nānā ʻana i ke aniani, ʻo ka ʻike o nā mea nui e like me ka potassium a me ka sodium, nā waiwai kino e like me ka porosity a me ka nui o ka particle pono e hoʻokō i nā koi kikoʻī a mālama i ka paʻa pili.

Pono e mālama nui ʻia i ka wā o ka sintering haʻahaʻa haʻahaʻa o nā billet i kaomi ʻia. Ma muli o ka palupalu o ka molybdenum, ʻaʻole hiki ke hoʻomaʻalili koke ʻia nā billet. ʻAʻohe o ka sintering a i ʻole ka hoʻoluʻu ʻana, pono e loaʻa kahi ʻāpana pale wela e pale ai i ka haki. Pono e hoʻomalu maikaʻi ʻia ka manawa a me ka mahana o ka sintering haʻahaʻa haʻahaʻa, no laila ʻaʻole hiki i nā billet ke wehe wale i nā haumia haʻahaʻa haʻahaʻa, akā hoʻomaikaʻi hoʻi i ka ikaika a me ka conductivity, kahi kūpono i ka hoʻoheheʻe ʻana i ka vertical melting.
